Overview

The NSW2020-16T2GC-POE-IN is an unmanaged 19-inch rack-mount Fast Ethernet PoE switch with 16 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus two 1000Mbps Combo RJ45/SFP uplinks (G1/SFP1, G2/SFP2), built for machine-room and wiring-closet camera aggregation with independent fiber or copper uplink paths. It delivers a 250 W total PoE budget (30 W max per port, IEEE 802.3af/at, both Mode A (1,2/3,6) and Mode B (4,5/7,8) pinout support) over a 7.2 Gbps switching fabric with 5.36 Mpps forwarding, a 4M bit packet buffer and a 16K MAC address table, cooled by a single internal fan and powered from a built-in AC 100–240V supply (265 W max). The all-metal 440×195×44 mm 1U chassis (2.07 kg) runs from 0°C to 45°C and switches between Default (Normal), VLAN (Secure, downlink-to-uplink only, with PD keepalive to reboot unresponsive PoE cameras) and EXTEND (250 m surveillance reach) via a front-panel slide switch — no management software required, NDAA compliant.

Is This the Right Fit?

Six real deployment scenarios matched to this model's actual datasheet specifications.

16-Port Fast Ethernet PoE Bank Feeds a Full 16-Channel NVR16 PoE-enabled ports power and connect a complete 16-channel NVR from a single 1U switch — one device covers a full camera bank without splitting cabling across multiple small switches in the rack.

Two SFP-Ready Combo Uplinks for Independent Fiber and Copper PathsG1/SFP1 and G2/SFP2 are both Combo ports that take an RJ45 copper run or an SFP fiber transceiver — run one uplink over fiber to a distant core switch while the second stays on copper for a local NVR, or fiber both for a redundant dual-homed link, without needing a separate media converter.

Mode A + Mode B PoE Pinout Covers Mixed-Vendor PD CamerasUnlike single-pinout PoE switches, this model powers PDs wired to either Mode A (data pairs 1,2/3,6) or Mode B (spare pairs 4,5/7,8) — useful when a project mixes cameras or PD devices from different vendors without needing to check pinout compatibility port by port.

Priority Ports 1-8 Keep Core Cameras Powered When Demand PeaksPorts 1-8 carry PoE power priority, so entrance, server-room or other critical cameras wired to those ports keep drawing power first if combined demand across all 16 ports approaches the 250 W budget.

VLAN Secure Mode with PD Keepalive for Unattended Equipment RoomsFlip the front-panel switch to VLAN (Secure) mode so downlink ports can only reach the uplink, and let PD keepalive auto-reboot any camera that stops responding — cutting truck rolls to remote server rooms and wiring closets.

EXTEND Mode Pushes a Perimeter Camera to 250 m From the Same RackFlip the same front-panel switch to EXTEND (surveillance mode) to push power and data up to 250 m for a single gate, fence-line or driveway camera — no separate mini switch or repeater needed near the main rack.

Not a good fit if:

Downlink ports are Fast Ethernet only (10/100Mbps, no Gigabit) — for 4K or multi-stream cameras that need gigabit throughput per port, choose a Gigabit PoE switch; only the two Combo uplinks (G1/SFP1, G2/SFP2) run at 1000Mbps.
Unmanaged — no Web/CLI/SNMP access or per-port VLAN tagging; the front-panel switch offers only Default/VLAN/EXTEND positions, not granular configuration; choose a managed switch if you need remote monitoring or individual port control.
250 W total budget can't power all 16 ports at 30 W simultaneously (16×30 W = 480 W ≫ 250 W) — plan camera load around the 8 priority ports, and note this model is 802.3af/at only, so 802.3bt high-power PTZ domes (60–90 W) need a bt-capable switch or injector.

16-Port PoE Switch FAQ — NSW2020-16T2GC-POE-IN

How many cameras can the NSW2020-16T2GC-POE-IN power?

All 16 × 100 Mbps ports source IEEE 802.3af/at PoE from a 250 W budget — roughly 15 W per camera fully loaded, well above the 4–12 W a typical fixed IP camera draws. A single port can supply up to 30 W for PTZ or heated housings, so 16 cameras including a few PTZ is workable.

Why two combo SFP uplinks instead of one?

The two 1000 Mbps Combo ports (G1/SFP1, G2/SFP2) each accept RJ45 copper or an SFP fiber module, giving independent uplink paths. Installers typically run fiber to a remote control room on one and copper to the on-site NVR on the other — no media converters needed on either path.

Can it reboot a frozen camera by itself?

Yes. In VLAN (Secure) mode the PD keepalive function watches each PoE port and automatically power-cycles a camera that stops sending data for a set period — a built-in PoE watchdog. The front slide switch also offers Default mode and EXTEND mode, which reaches cameras up to 250 m away.

Will it power cameras that use different PoE pinouts?

Yes — it supports both Mode A (pins 1,2/3,6) and Mode B (pins 4,5/7,8) to IEEE 802.3af/at. Mixed fleets of cameras from different brands, plus older powered devices tied to one pinout, all negotiate power normally on the same 16 ports, which cuts troubleshooting time on retrofit jobs.

What are the power, cooling and compliance details?

A built-in AC 100–240 V, 50/60 Hz supply powers the 19-inch 1U chassis (440 × 190 × 44 mm, 2.07 kg), with 265 W maximum consumption and one internal fan, operating 0–45 °C. It is NDAA compliant, ports 1–8 hold PoE priority, and the 7.2 Gbps / 5.36 Mpps fabric carries all 16 streams.
